(Cl-221-9'5) This invention pertains to a liquid dispensing apparatus and more particularly to a construction thereof wherein the meter, air separator and registering assembly may be readily disassembled from said apparatus asa unit for test or other purposes.

, It is an object of this invention to provide a liquid dispensing apparatus having a meter, air` separator and registering mechanism'assembly, which readily may be replaceable as such.

Another object of the invention is to provide a compact assembly comprising a meter, air separator and registering mechanism which readily may be applied to a liquid dispensing apparatus or readily may be operated asan assembly as for test purposes, separate from the liquid dispensing apparatus with which it is adapted for assembly.

AStill another object of the invention is to provide a liquid dispensing apparatus which is adapted for manual operation and wherein a simple, inexpensive interlock may be provided for preventing dispensing of liquid from said apparatus subsequent to a dispensing operation until the, register has been reset to a predetermined posii tion.

A further object of the invention is to provide a liquid dispensing apparatus which'is of rigid construction, but wherein the bracing mechanism for the separate units `is simplified and reduced to a minimum.

With these and various other objects in view,` the inventionmay consist of certain novel features of construction and operation as will be more fully described and particularly pointed out in the specication, drawings and claims appended hereto.

Figure '7 is an enlarged sectional elevation ofthe delivery flow control Valve provided in the interlock arrangement of the liquid dispensing ap-pA 5 paratus illustrated in Figure 1 Figure -8 is an enlarged sectional elevation of the valve construction illustrated in Figure '7, the same being taken substantially in a plane at right angles to the plane in which the section of Figure 10 7 is taken. l

In the device illustrated, the liquid dispensing apparatus consists essentially of a base I0, for supporting the casing I2, the casing being of any particular outside configuration, the casingbe-'l I ing/made rigid by. the internal vertical bracing members I4 and the transverse platform or supporting member I6 suitably secured, as at I8 and 22 to the vertical bracing. A pump 20 of the rotary Ipositive displacement type isv suitably 20 secured to the under side ofthe platform I 6, said platform being secured to suitable braces of the casing as at I8 and 22, the pump being adapted to be operated by means `of the pulley or gear 24 provided on the rotor shaft- 26. The gear 24 is 25 connected by means of the chain or belt 28 to the gear 30, said gear being pivotally mounted as at 32 on the bracket 34 suitably supported on the platform I6 and ybeing securedthereto as at 36. s

'I'he shaft 32 is adapted to rotate with pulley 30 30 and is provided with the pulley or gear 38, the gear 38 being connected by the chain or belt 40 `to the `gear or pulley 42 pivotally mounted on the bracket 34 as by means of the shaft 44, the shaft extending suitable means to receive an operating member such asa crank for rotating the ygear 42, which motion is transmitted to the pumpy operating gear 24 by the train described. A suitable slack adjuster 46 is pivoted as at 48 lto the bracket 34 40 and #adjusted so thatmeans such as a roller 50 eng ges the chain 4I) to take up any slack due The pump 2l) is provided with the inlet 52 supply not shown, the `outlet side of the pump with a coupling fitting 56. The coupling fitting 56 is adapted to engage and be secured to 'a corresponding coupling iltting 58 of the pipe 60 as at 62. 50 The pipe 60 is connected to the inlet side of the air separator 64. The outlet side. of the air separator is adapted to be connected to the inlet side 66 of the meter 6B; the outlet side of the meter being provided with the pipe 'III having a' cou- 55 i pling fitting 12 thereon. The air separator is also provided with a return tting 14 adapted to be connected to a return pipe 16 which in turn is adapted to be connected to the inlet side of the pump 20 as through the fitting 11.

The vent of the air separator is adapted to be connected to the vent pipe 18 through the fitting 19, said vent extending upwardly and exhausting through the atmosphere at the high point in the apparatus such as shown at 80. The meter is` v provided with the meter shaft 82 adapted to be rotated in accordance with the liquid passing therethrough and is operatively connected to the rotating shaft 84 of the registering mechanism 86, said registering mechanism being of a construction such as illustrated in Patent No. 2,149,- 609 to Lennart, granted March '7, 1939. The registering mechanism 86 is adapted to be supported on the bracket 88, the bracket comprising the depending body portion 90 having suitable reinforcing i'langes or ribs 92, 94, 96, 98, |00 and |02 and being adjustably secured and supported as at |04 on the air separator 64 through the elongated apertures |06. The upper flange |08 Iof said bracket is provided with the spaced legs I0, provided with elongated apertures |2 for accommodating suitable securing means ||4 whereby the registering mechanism 86 is adjustably supported on said bracket.

The registering mechanism is provided with the reset shaft ||6 provided with the clutch ||8, said clutch being engaged by the yoke |20 provided on the interlocking rod |22, said rod being provided with the spring |24, normally urging said clutch toward engaging position. The clutch is connected through the jack shaft |26 and suitable gearing |28 to the reset knob |30, the said gearing being supported through the bracket |32 secured to the bracket |34 provided on the vertical framing. The bracket |36 is also supported on the vertical framing and provides a support for the bracket |38 to which the lever |40 is pivoted as at |42, the lever |40 being adapted to be moved with the lever |44. The lever |44 is connected as at |46 to the rod |48, said rod being pivotally connected as at |50 to the arm |52 of the bell ,crank |54, said bell crank being pivoted' as at |56 to the bracket |60 which is extended outwardly of the pump casing and provides a nozzle support. The arm |52 is adapted to be engaged by the push button |58, said push button being disposed above the nozzle support and the lever |62 preferably is disposed in' an overlying relation to the push button |58, being pivoted as at |64 to the pump casing.

The bell crank |54 is also provided with the depending arm |66 adapted to be engaged by the push button |68 disposed below the nozzle support |60. The inwardly extending arm |10 of the bell crank is pivotally connected to the rod |12, said rod, extending upwardly, being pivotally connected as at |14 to the bell crank |16 provided on the valve shaft |18 of the delivery ow control valve |80. The valve is connected at its inlet side to the pipe |82, said pipe extending downwardly therefrom, being connected to the expansion valve housing |84 and through said housing to the coupling |86, which in turn is suitably connected to the coupling 12 as at |81. The outlet side of the valve is connected to the discharge pipe |88, which in turn is connected to a suitable sight gauge to which the dispensing hose (not shown) is connected at |92, the other end of the hose being connected to the dispensing nozzle 94;

75 said nozzle is shown being supported from the nozzle support 60, in which case the nozzle valve cannot be operated.

When in supported position the lever |62 is depressed inwardly, preventing movement of the push button |68 inwardly. The valve |60 is provided with the valve seat |96 for the valve member |98, said valve member being fixed to they shaft |18. The bell crank |16 is provided with one leg 200 to which the rod |12 is pivoted as at |14 as already described, the other leg 202` being pivotally connected as at 204 to the contractile spring 206, the opposite end of said spring being pivoted as at 208 to the .valve housing. It will thus be seen that the spring forms a means of biasing said valve so that it may be snapped to either open or closed position, depending upon which side of the dead center, that is, on which side of shaft |18 the spring 206 is disposed.

The registering mechanism, air separator and meter are fixed through the base 209 as by the bolts 2|0 to the brackets 2|2 supported on platform I6 so that, together with the piping, these units are maintained in a rigid and fixed position, yet may be readily removed, as will be more fully described.

In operation of the liquid dispensing apparatus, assumingv that the register has been set to a predetermined or zero position, the nozzle |94 may be removedfrom the support |60 and the push button |68 maybe pushed inwardly, causing the push button |58 to be moved outwardly. Movement of the push button |68 inwardly also causes the rod |48 to be moved upwardly whereby the lever |40 compresses the spring |24, causing the clutch ||8 to be moved to declutched position. The rod |12 is moved upwardly, moving the valve member |98 off its seat, |96, causing the lever 202 to be moved until the spring 206 passes dead center, at which time the valve member |98 is quickly moved to fully open position. The crank (not shown) may then be rotated to cause rotation of the gear 42, which in turn causes operation of the pump 20 for causing liquid to be drawn fromA eration the hose nozzle |94 may be replaced on its support |60, which causes the push'rod |58 to be moved inwardly, releasing compression of the spring |24 and permitting the clutch ||8 to be moved .to clutched position, at which time the register may be reset. The rod |12 is also moved downwardly, causing the valve member |98 to be moved toward closed position, moving the. lever 202 until the spring 206 passes dead center, at which time the valve will be snapped to closed position as illustrated in Figure 7.

Under certain conditions the authorities who from time to time test liquid dispensing apparatus may prefer to test the essential units at some pl'ace distant from the liquid dispensing apparatus. In many instances this is desirable on account of the complicated testing machines sometimes necessary to be used, and under those conditions, of course, it would be very undesirable to remove the entire liquid dispensing apparatus and send it to the point of test.- With this in mind the present liquid dispensing apparatus is so designed that the measuring and Vindicating mechanism may readily be removed. suitably boxed, and sent to tie point of test.

In this instance the drain plug of the valve tting |84 is removed and the valve therein is '64, and the vent pipe 18 can be removed from the coupling 19 of the air separator 64. The bolts 2|()v under the meter 68 are removed,.releasing the fastening of the meter to the brackets 2|2 supported on the platform` I 6, and thereafter the fastening means 62 are removed from the coupling members 56 and 58. The entire unit, that is, the register, air separator andvmeter, can then be lifted .bodily from the liquid dispensing apparatus, leaving the apparatus as shown in Figure 2, and said unit can be shipped to the desired place for testing.

When the unit isvreturned it may readily be replaced or installed by placing the unit in the liquid dispensing apparatus in a position that the set back shaft IIB is properly aligned with the gear mechanism |28 in order to permit the in- `sertion of the jack shaft |26. The interlocking rod |22 is disposed so that it is back of the lever |40 which is readily accomplished, particularly if the hose nozzle is permitted to remain on the support |80. Afterthat the gaskets are properly replaced between the flanges of the coupling members 12, |86, 56 and 58 and the securing means is applied to tightly fasten the coupling members together, it being understood, of course, that they will not be tightened until all of the fastening means is in place, including the fastening means 2| 0 of the meter 68to the brackets 2|2. The tubing is then all connected, that is, the tube 16 is reconnected to the air separator 64 and -the pump 20, and the vent tube 18 is reconnected to the air vent of the air separator 64. The drain plug is then tightened in the member |84 and the apparatus is ready for operation.

It -is to be understood that I do not wish to be limited Vby the exact embodiment of the device shown, which is merely by way of illustration and not limitation, as various and other forms of the device will of course be apparent to those skilled in the art without departing from the spirit of the invention orthe scope of the claims.
